marine life which is causing zooplankton and fish to migrate to cooler regions. The reason for this is the decrease in the growth of phytoplankton as a result of the reduction of nutrients in the environment. Warmer regions are less dense than colder regions, which are deeper and have better nutrients. Since the warmer regions have a lower density, exchange of water between the two regions was reduced. As a result of this decline, the migration of fish and zooplankton has
Steinbeck's View of the World John Steinbeck's novels expressed an ecological world view that has only recently begun to accumulate proponents. This holistic view grew during an era when such thinking was unpopular, and one must wonder how this growth could have occurred in a climate which was hostile for it. Some investigation shows that the seeds for this view already existed in his childhood and were nurtured through his exposure to ideas in marine biology. While growing
able to convert carbon dioxide into carbohydrates and oxygen used for life (through photosynthesis), and they account for about 95% of the ocean’s primary productivity, while providing about half on Earth. Phytoplankton is a primary food source to zooplankton and the rest of food web in the ocean. The marine food web is really important to understand as it has many levels as we do ourselves and on land. The larger animals eat the smaller animals and it continues to the smallest organisms that are found
Introduction Zooplankton is a very diverse group of organisms that form an integral part of the microscopic animals that make up plankton in the water columns of lakes, ponds, rivers, estuaries and open-ocean. These organisms play important roles in the aquatic food web and can greatly affect fisheries among species that rely on a diet of zooplankton early in their life cycle. Taking the time to study these microscopic organisms would be beneficial in regards to understanding the early lives of larval
Giant Otter The mammal that I have chosen is the giant otter. I was interested in this mammal because I did not know there was such thing as a giant otter. I mostly thought that there were just normal sized otters. Now I’m intrigued to know what the giant otter’s life is about. Where are they from? I will be finding out this information later in my paper. They are nice, but violent creatures. The giant otter species is lutrinae. The lutrinae is a branch of the weasel family Mustelidae. That family
Marine Science Essay By Rudolph Wilson What are invertebrates and vertebrates? Vertebrates happen to be animals that have an internal skeleton which has a backbone and they also have a spinal column. There are five classes of vertebrates there are fish amphibians, reptiles, birds, and mammals. They happen to be very large in size and very we'll developed there body contains a functional a heart split between two or four chambers. Basically the main features for vertebrates is a vertebral column
Marine Careers Marine biology is the field of knowledge relating to any kind of marine organism, dolphins, whales, sharks, seals, plankton, etc. But what is a marine biologist? Well to a lot of people, the first thing they think of is Shamu and training dolphins but to others it means managing a marine wildlife sanctuary. There are multiple answers to this question and none of them are wrong answers, but to me a marine biologist is someone who has anything to do with the marine life, whether it be
do to humans. She could have explained that some zooplankton is weak against acidification, and since they assist in absorbing the carbon dioxide, it could be detrimental for humans to see these types of microscopic organisms become scarce. For, if they do, there would be even more carbon in the atmosphere, which would make it harder for humans to breathe. In addition, the lack of zooplankton would result in a decline of biodiversity, as zooplankton are the basis for various food webs. Less marine

Plankton are organisms in the ocean that drift with the currents. This includes phytoplankton and zooplankton. Phytoplankton are plant plankton or some are bacteria that they contain chlorophyll and want sunlight in order to grow and live. It lives in watery environments both salty and fresh. Some phytoplankton can improve nitrogen and can grow in low concentrations
Animal captivity is a much discussed issue for both its benefits and detriments to the animals. Many people view animal captivity as a harm and believe that it should be stopped; however, what is not taken into account is its benefits. Animal captivity aids both animals and humans in multiples ways, but the majority of help animal captivity offers is through preservation of animal species, and education benefits that zoos and aquariums represent to man. The preservation of animals must continue so
Competition and predation are two key factors that affect the stability of an ecosystem, such as a lake. There are three theories on the affects of competition. Competition may lead to competitive exclusion, stable coexistence, or niche differentiation. It has been shown that in marine environments, species are strong competitors for both light and nutrients and thus competition leads only to competitive exclusion (Passarge et al. 2006). The competitive exclusion principle states that if two
Ocean acidification The oceans take up carbon dioxide from the atmosphere and are responsible for absorbing around a third of the carbon dioxide roughly 22 million tons a day emitted by fossil fuel burning, deforestation, and cement production since the industrial revolution (Sabine et al. 2004). While this is beneficial in terms of limiting the rise in atmospheric carbon dioxide concentrations and hence greenhouse warming due to this carbon dioxide, there are direct consequences for ocean chemistry
scientifically formulated diets using fish meal are available for zebrafish. However there is a large gap between these diets and the zebrafish’s natural diet, as commercial diets are based on fish meal and plant meal while wild zebrafish consume zooplankton, insects and algae. Also, among commercial diets, performance outcomes of these diets are vary significantly and there are no clearly established standards. The insect based diet could be a standard diet option for zebrafish, as zebrafish naturally
The Giant Oarfish Cool Facts: The giant oarfish has a number of characteristics which makes it unusual. One fact is that it is the longest bony fish alive today- up to 36 feet long (11 meters). A second fact is that, since it sometimes floats on the surface of the ocean when it is sick or dying, it may be the source of the idea of sea monsters. A third fact is the entire taxonomic family to which the oarfish belongs consists of only four living species. Taxonomic Information: The scientific
weeds. The weeds act as a shelter for fish larvae and zooplankton, both of which eat algae and are, in turn, eaten by larger fish. Scientists have concluded that unpolluted lakes can absorb surprisingly large amounts of phosphates without uncertainty. When a fertilizer, such as a phosphate, is added more algae will grow, and consequently will the populations of zooplankton and fish. Difficulties only arise when the lake is already impure. Zooplankton are sensitive to their environment and many substances
Humans have spent billions of dollars, and millions of man hours conducting research of sea life. As technology advances and the ability to stay underwater for longer periods of time become available, new information about sea life and there ecosystems surface. The vast ocean covers more than 70 percent of planet Earth’s surface (NOAA). However researchers and scientists have explored less than five percent of what really lies under water (NOAA). Leaving behind and amazing ninety-five percent left
Plastic is the most harmful form of debris to marine life because it has the tendency to break down into minute sizes similar to zooplankton, which is a major food source to some marine animals. Micro-plastic concentrates in the surface water of the ocean, where many zooplankton and additional food sources live. Organisms that come to the surface to feed on zooplankton instead consume astounding amounts of plastic. These plastics do not provide nutritional value as well as introduce potential dangers
causing harmful algae blooms when there is an abundance of nutrients. Phytoplankton also serve as the main food source for a larger but still microscopic organism named Zooplankton. Marine Bio.org did a study on zooplnkton revealing that they are very weak swimmers making them an easy food source for any larger organsim. Zooplanktons’ main purpose serves as the main food source for small fish and
The concept of the microbial loop first began in 1926 by Vernadskii, who studied heterotrophic and phototrophic microbial metabolism; and understood that these systems represented a major part of total metabolism in the oceans (Pomeroy, 1988). Older techniques that scientists used for enumerating marine bacteria were by plate counts, serial dilutions and phase-contrast microscopy. These numbers represented about 10% of actual numbers and are no longer used (Azam et al, 1983). Scientists were unable
